There is this real misconception that somehow, if your feet are not on the ground when you bump someone, then you are in deep s**t. That is a fallacy.
Whether your feet are on the ground or not has absolutely no baring on whether the bump/collision is within the laws of the game so I would suggest that people stop making a song and dance about whether or not the player bumping is off the ground.
In this Harvey case, he bumped a bloke who was miles away from the ball/the play and caused him to leave the ground with the blood rule. Last year, Jonas from Port Adelaide dished out a text book bump on an opponent but the trouble was that the opponent was miles away from the ball/the play and from memory, he was rubbed out for four games!
This tribunal fiasco is an incredible embarrassment and a blight on Aussie Rules Football.
To show just how ridiculous the rules of this great game have become, look no further than the ludicrous "play-on-to-advantage" law of the game. It is the only sport in the world that I can think of where the players adjudicate a law, that is, they can choose to play on or stop when a free kick has been awarded to their team. That's a disgrace!
Umm...NRL? Soccer?
